Like we've said before they all use the same switches. The core guts of the keyboards are all the same. It comes down to build quality, keycap quality and extra electronics features. Keycaps especially is probably the biggest factor since the cost between pad printing vs laser vs dye subs is very different. And stop searching for "gamer" keybaords if you don't want a gamer keyboard. There are plenty of keyboard brands out there (DAS, Filco, Leopold, Topre, Happy Hacker) that don't give two fucks about macro keys and backlighting.
